Airtac ACQD Double Acting Compact Cylinder ACQD25X25B
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD25X25B is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø25mm bore and 25mm stroke. The twin rods resist rotation and give equal push and pull force, so it carries and guides a tool platform without a separate anti-rotation guide.

About the Airtac ACQD Double Acting Compact Cylinder ACQD25X25B
The AirTAC ACQD25X25B is a double-acting JIS compact cylinder where a Ø12mm piston rod protrudes from both ends. Because a rod occupies each pressure chamber, the annular area is identical on extension and retraction, yielding equal force both ways at 188.9N (0.5MPa) and 264.5N (0.7MPa). This symmetric thrust is ideal for push-pull cycles requiring consistent momentum.
Twin rods drastically increase guide length and prevent platform rotation without needing an external guide rail. The body features fixed TPU elastomer bumpers at both ends for end-of-stroke deceleration, plus magnetic-switch grooves. This variant includes an M10x1.25 male rod-end thread for direct load coupling, though it ships without a sensor magnet.
Airtac ACQD Double Acting Compact Cylinder ACQD25X25B Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD25X25B |
|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø25 mm |
| Stroke | 25 mm |
| Acting type | Double acting, double rod |
| Port size | M5×0.8 |
| Rod end thread | M6×1.0 female / M10×1.25 male (B) |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.15 – 1.0 MPa |
| Proof pressure | 1.5 MPa |
| Temperature | -20 to +70 °C |
| Speed range | 30 – 500 mm/s |
| Cushion | Bumper (both ends) |
| Max standard stroke | Up to 100 mm |
Specifications follow the official AirTAC ACQD datasheet. A rod exits both ends, so both directions use the same annular area. Confirm against the product label before installation.
Theoretical Output Force (Ø25mm — equal both ways)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 189 N | 189 N |
| 0.7 MPa | 264 N | 264 N |
| Max (@1.0 MPa) | 39 kgf | |
Because a rod occupies both chambers, push and pull forces are EQUAL — the annular area applies in each direction. Actual usable force is lower due to friction; size with a safety margin.

Where the Airtac ACQD Double Acting Compact Cylinder ACQD25X25B Is Used
Symmetric Transfer Pusher
Drives a dual-sided transfer arm in packaging lines, using the equal push and pull forces to maintain consistent indexing speed in both directions.
Twin-Guided Pick & Place
Handles small electronic components where the second rod prevents tool rotation, eliminating the need for a separate anti-rotation guide bearing on the actuator body.
Dual-Station Actuation
Powers a diverter gate on a conveyor system, using the opposing rod end to mount a mechanical flag or secondary linkage for synchronized operation.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD25X25B the Right Cylinder?
Providing 39kgf max at 1.0MPa, this 25mm bore unit sits between the 20mm ([email protected]) and 32mm ([email protected]) sizes for equal bidirectional thrust. Choose the 20mm if your cycle requires less energy, or the 32mm for heavier transfer loads. If your mechanism already has an external linear guide and you simply need basic actuation, a single-rod ACQ might suffice. Confirm your stroke needs (max standard 100mm) and specify the -S magnet option if position sensing is required.
Quick checklist
- ✓ Equal force both ways at your pressure
- ✓ Anti-rotation needed (twin rods)?
- ✓ Both rod ends usable for tooling?
- ✓ Magnet (S) for sensors?
- ✓ Female (blank) or male (B) rod thread
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Both rods share the load — keep force concentric.
- check Twin rods resist rotation but avoid heavy side load.
- check Handle the C-clip carefully; seat it fully in its groove.
- check Installation by qualified personnel per AirTAC docs.
Airtac ACQD Double Acting Compact Cylinder ACQD25X25B FAQ
The ACQD25X25B delivers an equal push and pull force of 188.9N at 0.5MPa and 264.5N at 0.7MPa, with a maximum holding capacity of 39kgf at 1.0MPa. Push and pull forces are identical because the double-rod design creates the same annular piston area in both directions. The maximum standard stroke available for this 25mm bore is 100mm.
The twin-rod structure inherently resists rotation and provides extended guide length for the tool platform. It uses fixed TPU elastomer bumpers at both stroke ends rather than adjustable air cushions. A plain ACQD does not hold its load if air pressure is lost; for fail-safe positioning, you must install an external rod lock or pilot-operated check valve.
